Ok, so we don't know which physical transponder is sending out the virtual 103(s) tpn 21, but since they are all using the same TID, they're from one physical transponder. We just don't know if that's from D10 or D12.

Either way though, they're still putting 9 LiL HD channels into one frequency range, right? Putting 9 channels into the bandwidth of one transponder?

Everything is correct. Almost. You missed just HoTat2 reply : tp. 21 is A4BC at 103(s)I would try to see if the TID#188 spilling to my territory - perhaps I could provide some additional info for you ...

Well here's the beam pattern of A4BC that is for the Portland DMA. I'm located due north of the "tack" on the map, right on the north/south stretch of the Columbia River.

My dish is well aligned (99c strengths in the 90's) and I get 97 for my signal strength on 103(s) tpn 21. It used to be a consistent 100 before D12 went up. Not sure if that means anything...

Not knowing where you live, I can't tell if the beam falls into your "territory".

EDIT. Nope, can't lock on it here. H23 is reporting "Not Acquired" and a signal chart below telling me, the dish is properly alignment (see that spikes to 10 or 20 dB) - it's just orientation of antenna's reflector and whole sat (with its little precession) allow see the signal for short bursts.

According to Doctor j's spotbeam map, the spotbeam covering the Portland market using tp. 21 is A4BC at 103(s).

That's Antenna 4 beam 12 emanating from either D10 or D12. Now at the time Doctor j produced the document their were 7 HD locals active there.

KATU-2KOIN-6KGW-8KOPB-10KPTV-12KPXG-22KRCW-32

Now since then add;

KUNP-47KPDX-49

And that's 9 total for tp. 21 on SB A4BC at 103(s)

Counting separate PIDs for the tp21 [TID 188]: it is 9 separate channels there. No mirrors. If it will cover little south then we could measure bit-rate or each channel/PID ...

Is it a Record for Ka tpns? Or DTV will follow a competitor and will compress LiL more and more. For now 103 tp 12 and 13 (CONUS) running 7 channels too. Also many spot-beams at 99W and 103W - just sort by a column VPID to discover the numbers.

Interesting tidbit: PID 1091h is assigned and used for Ka tpn's Test Messages (ch 95xx), so it was projected up to 8 channels per Ka transponder from beginning (PIDs 1010h...1080h). As to tweaking FW of statmuxers last months, I didn't buy it from beginning that count must be 6 and no more. Perhaps the manufacturer didn't fulfill original DTV's specs in FW versions up to last months.

Well, thanks for giving it a shot. Road trip?

They must be using a different modulation on some spot beams compared to the CONUS tpns in order to increase the bit rate for all those LiLs, you think?

What's stopping them from going QPSK 4/5 47 on CONUS feeds if these LiL's are testing OK? Rain Fade considerations?

I don't think I could trust 8PSK on Ka without a poor rain fade experience, but it would be worth seeing test data and signal measurements. I say, DirecTV be adventurous and put HD channels people really don't care about in a 9:1 mux using 8PSK (stuff like CSPAN's, Shopping, Religious, etc..) just to see what happens.
